Welp it is time for a new project and I need some help getting started!

I have a friend that has a rather expensive watch. These watches are self winding, but that requires that you actually do stuff all day. His never gets fully wound (sp?) then he takes it off for the night and it stops in the middle of the night. It is not good for a"good watch" to be stopping and starting all the time.Hence the watch winder. They sell them. They are expensive.Here is a link to a few just for those of us (myself included) that may never own a $10,000 watch

My friend bought a watch winder and it simply was not powerful enough to turn his watch. The watch is heavy (1LBS)

Simply put Im going to build him a watch winder. I know this will require little more then a motor and some arduino logic. The problem lies in the fact that while I do have some exp with the ardunio (search for my RFID door) I do not have any exp with motors. The other part of the puzzle is that the motor needs to have a jerking motion (E.G. 1/4 turn then a jerk 1/8 back)Based on my limit knowledge on the subject im thinking a stepper motor would do the trick, but im calling on the pros (all of you guys) to help me out with any ideas, brainstorms and motor suggestions.

Im not sure if this is the correct forum to post this in, but I couldnt think of any better.

Unfortunately steppers can be a bit noisy also although you can mitigate it somewhat with microstepping. If you go that route the Easydriver board from Sparkfun is a good, inexpensive and very compact solution.

You don't really need an Arduino or anything complex in all of this; the watch just needs some rocking motion of some sort. A cheap gearmotor, and some handywork, maybe a wall-wart sized for the motor, and a switch.

I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

I agree with cr0sh.A continuous rotation servo would be rather whacky though... might aswell use a proper motor in that case. But really, this application has extremely simple logic: rock the watch while a switch is flipped. No need to use any kind of controller.. just put the switch on the power supply (if that, you could also simply leave it as a 'unplug the power to turn it off' device).
